-' To @ZZ whom it may concern:

Be it -known that I, CYRUS R. MILLER, a citi- I zen of the United States, residing at Milwau? kee, in the countyof Milwaukee and State of Wisconsin, have invented certain new and useful Improvements. in Bag-Dusting Ma-` the following is a specifica- The apparatus, which forms'the subject-V matter of this application and which is shown in a preferred form, consists generally kof a and rotatably mounted within the casing, of

.driving means for the beater-arms.

casing, a cylindrical drum or cage having 'its sides coveredwith wire-netting", expanded Inetal or other form o'fA reticulated metal beater-arms mounted to rotate in a direction opposite to that of the drum, of wings or fanblades on the cage adapted todrive the dust from the cage, and of a spout or'chute through which the extracted dust is driven from the casing.

Certain details of construction and arrangement will be hereinafter set forth.

n the accompanying drawings, which form a part of this application, Figure 1 is a vertical longitudinaly section through the center of my improved apparatus. Fig. 2 is a horizontal cross-section through the machine. Fig. 3 is a side elevation of the machine, showing Fig. 4 is an enlarged detail of a portion of the beaterarm shaft, and Fig. 5 is a cross-section of same on-line 5 5 of Fig. 4:. v Y

Referring to the details of the drawings, A and A', respectively, represent the upper and lower-sections of the cylindrical casing, which are secured together by iianges a2 and form a housing for the operative parts of the apparatus, to which access is had by means of a door as, hinged at a4 on section A' and latched at as on section A. From one side of the casing extends downwardly a spout B, which may be connected with any suitable means, for carryingaway or receiving the dust which is driven into the spout in a manner'to be expari-,s to be' described. Extending through the casing and eccentric thereto isa shaft F, Von which is keyed a pulley f', which is driven from any suitable source and in any approved manner, and on the opposite endof the shaft lis a smaller pulley f5.` J ournaled on the shaft are hollow' trunnions fzjs, which are 4,bolted to the respective heads of the cage C, Onthe trunnion f3 is fixed apulleyff, which lis driven by a belt f7, which, after passingy around pulleys f6 f5, travels over the pulley f5 on the4 shaft F, by which it is driven. The

' pulleys j' 6 are mounted on suitable stud-shafts .extending from the portion a7 of the frame..

This arrangementof pulleys and belt effectsv the driving of the cagcin a direction reverse to that of the shaftv F, as will be readily under'stood'. v

On the shaft F within the cage is a drum E, which is made injsemicylindrical sections,

secured together and. bound on the shaft by bolts c2, as indicated `by dotted lines, Fig. 5. Extending radially from this drum and staggered are a plurality of beater-arms e', which are preferably made of leather, but may be of any suitable flexible material. These arms pass through the \walls of the drum E and have their inner ends bent up, as at e", and secured by screws, as clearly indicated in Fig. 5.

The cage C is made up of woodenends, through which are cut openings c3 of rings D, which are securedA to the inner sides of the ends, and of .wire-netting d', which is secured to the rings and forms a cylinder, access to the interior of which is afforded by a hinged door d2. Connecting the two heads ofthe cage and extending radially from the cage are blades c c2, the'former projecting outwardly from the cage and the latter inwardly relative to the cage. The wings c are preferably inclined away from the direction of rotation of the cage, which is indicated by an arrow in Fig. 1. The direction of rotation of the beater'- arms is indicated by an arrow in Fig. 1. It will be noted that the cage is concentric with the shaft F and is therefore eccentric to the casing, thus bringing it nearer the spout B.

An apparatus constructed and arranged as described will operate as follows: Assuming thatpower is applied to thepulley f and that dust-laden bags/have been placed in the cage, the cage and beater-arms will be driven in opposite directions, as indicated, whereupon the bags will be thrown by centrifugal force against the wire -,netting, will be carried Patented Dec. 5,k 1905.

Ioo

around by the blades 02, and beaten by the arms e'. Air Will be drawn in through' the openings in the heads ofthe easing, and dust Will be driven out through the Wire-netting by centrifugal force and the revolving arms, and the blades c Will carry it,over the upper end of the spout B, through Which it Will be forced byl the draft thus created, it being understood, of course, that a suitable outlet is provided for the spout which will not check the draft.

There may be various modifications in the details of construction of my dust-extracting apparatus Withou'taffecting the principles involved therein. I do not, therefore, Wish to be limited by my patent to such details; but,

i What I claim, and vdesire to obtain by Letters Patent, is-

l. In a dust-extracting apparatus, a casing having a suitable discharge-spout, air-inlets and door, a cylindrical cage rotatably mounted in said casing and having its peripheryformed of reticulated material and provided with suitable air-inlets in its heads and having a door, flexible beater-arms mounted Within said cage to rotate in the direction` opposite thereto, and means for driving said cage and for operating said beater-arms.

2. In a dust-extracting apparatus, a casing having suitable ldischarge-spout at one side and for operating said beater-arms.

3.` In a dust-extracting apparatus, a cylindrical casing having suitable discharge-spout, openings in its heads and door in its periphery, a cage rotatably mounted within said casing, said cage having its periphery formed of reticulated material and provided with radial blades extending externally and internally from its periphery, said cage having a suitable door and with openings in its heads, ilexible beater-arms mounted in said cage and adapted to rotate in the direction opposite thereto, means for driving said cage and means for operating said beater-arms.

In testimony whereof I aix my signature in presence of two witnesses.
